We have a wonderful java applet that will allow you to find the name of any country shown on our maps from the history section. You can pick a year, zoom in on an area, and identify countries with your mouse. You must have a java-capable browser to use this interface.
For those of you who have difficulty with the above interface, we have several maps that feature modern areas of the world, allowing you to quiz yourself with an unlabled map before revealing the country names. These maps allow you to click a country, revealing the name of the country. Once you have zoomed in on a map, you can also click on rivers and lakes to identify information about them.
